ginasaur 

A woman past her "cougar" prime looking to hook-up with younger men. Commonly found at country clubs, crappy motel lobbies, flea markets, and dollar stores. In a nightclub environment will usually sport garish lipstick shades and reek of "lilac" perfume. Will travel in a pack of younger cougars and only be introduced to you once it has been confirmed that you have drunk so much that your judgement is incredibly impaired.

Dan: How was the club last night?
Ed: Decent, until I was approached by a pack of cougars.
Dan: C'mon bro, cougars are sweet!
Ed: Fo'sho! but after a couple of drinks they wanted to introduce me to a ginasaur...
Dan: Bad luck indeed, but you mighta scored a wicked "gummer".
Ed: Dude...that ginasaur was wearing 3 layer spanks!

An old grizzled woman that insists on showing as much leathery tanned skin as she can, in the hopes that she is still attractive.

Woman of advanced years engaged in sexual predation. Some authorities suggest a preference towards younger males a la Cougar while others point to a more general hunger for sexual validation from anyone whatsoever.
